The BFVA is a deeply eroded and dissected volcanic field dominated by multiple, several 10-m thick, valley-filling silicic ignimbrite units, which are chemically and texturally very similar to each other. Hence, establishing lateral correlation is a real challenge due to the sporadic and small-scale outcrops and lack of stratotypes. Detailed field observations allowed us to identify eleven lithological members including fourteen eruption events and establish a nearly complete lithostratigraphic correlation between fifteen outcrops across the BFVA. Primary pyroclastic material of each member was sampled, and volcanic glass was analyzed for major and trace element composition. The geochemical results confirm the field-based classification of the members and enable the correlation of distinct outcrops. The major and trace element composition of the glassy pyroclasts of each member of the BFVA served as basis to create a field-wide chemical reference database for regional correlational studies. Here, a new lithostratigraphic classification scheme consisting of one formation and eleven members is presented, which reflects the challenges unraveling the stratigraphy of ancient volcanic terrains. The field-based event-scale lithostratigraphy of the BFVA suggests a wet, partly sea-covered depositional environment in the close vicinity of the eruption centers providing favorable conditions to ‘fuel’ silicic explosive phreatomagmatism. On the contrary, paleosol horizons formed after almost each major eruption event or sequence suggests an overall near-coast terrestrial environment for the BFVA, where the emplacement of the pyroclastic material occurred.}, keywords = {STRATIGRAPHY; phreatomagmatism; ignimbrite; Correlation; lithostratigraphy; Glass geochemistry; Volcanic geology; Reworked pyroclasts}, year = {2024}, eissn = {1872-6097}, orcid-numbers = {Hencz, Mátyás/0000-0001-9716-5714; Biró, Tamás/0000-0001-5198-7210; Szabó, Csaba/0000-0002-1580-6344; Karátson, Dávid/0000-0003-0386-1239} } @{MTMT:33533651, title = {Integrating field volcanology, paleomagnetism and structural geology to correlate a poorly preserved Miocene succession in the East Mátra Mts.

Welded ignimbrites are usually resistant to erosion, thus, they often appear as positive landforms, i.e., mesas or tilted plateaus after millions of years of denudation. The Bükkalja Volcanic Area being part of the most extended foothill area of the North Hungarian Mountains, is composed predominantly of Miocene ignimbrites, where the frequency distributions of elevation a.s.l., slope, aspect, as well as topographic openness, were investigated using a 30 m resolution SRTM-based digital surface model at four sample areas located at different relative distances from the assumed source localities of the ignimbrites, showing both non-welded and welded facies. The degree of dissection was also examined along swath profiles. The topography of the sample area closest to the source localities is dominated by slabs of moderately dissected welded ignimbrites, gently dipping towards SE. Farther away from the source the topography is dominated by erosional valleys and ridges, resulting in a narrower typical elevation range, a higher proportion of pixels with greater than 5° slope, higher frequencies of NE and SW exposures, and more significant incision resulted in more frequent pixels with positive topographic openness less than 1.5 radians here. Higher thicknesses and emplacement temperatures of ignimbrites, often showing welded facies are more common closer to the source vent. Thus, the erosional pattern around calderas can be used to draw conclusions on the spatial extent of the most intense ignimbrite accumulation, i.e., the location of eruption centres even in highly eroded ignimbrite fields.}, year = {2022}, eissn = {2064-5147}, pages = {213-229}, orcid-numbers = {Biró, Tamás/0000-0001-5198-7210; Hencz, Mátyás/0000-0001-9716-5714; Telbisz, Tamás Ferenc/0000-0003-4471-2889; Karátson, Dávid/0000-0003-0386-1239} } @{MTMT:33116922, title = {Ipolytarnóc: egy 17,2 millió évvel ezelőtti, vei ≥ 7 robbanásos vulkánkitörés eseménysztratigráfiája}, url = {https://m2.mtmt.hu/api/publication/33116922}, author = {Karátson, Dávid and Biró, Tamás and Portnyagin, M and Kiss, Balázs and Paquette, JL and Cseri, Zoltán and Hencz, Mátyás and Németh, Károly and Lahitte, P and Mártonné, Szalay E and Kordos, L and Józsa, Sándor and Hably, L and Müller, S and Szarvas, I}, booktitle = {Calce et malleo – Mésszel és kalapáccsal}, unique-id = {33116922}, year = {2022}, pages = {64-66}, orcid-numbers = {Karátson, Dávid/0000-0003-0386-1239; Biró, Tamás/0000-0001-5198-7210; Kiss, Balázs/0000-0003-0040-0656; Hencz, Mátyás/0000-0001-9716-5714; Józsa, Sándor/0000-0001-8219-0044} } @{MTMT:33116913, title = {A Bükkalja miocén vulkánosságának eseményszintű rétegtana}, url = {https://m2.mtmt.hu/api/publication/33116913}, author = {Hencz, Mátyás and Biró, Tamás and Portnyagin, M and Németh, K and Szakács, A and Cseri, Zoltán and Pécskay, Z and Dávid, Á and Szabó, Csaba and Karátson, Dávid}, booktitle = {Calce et malleo – Mésszel és kalapáccsal}, unique-id = {33116913}, year = {2022}, pages = {55}, orcid-numbers = {Hencz, Mátyás/0000-0001-9716-5714; Biró, Tamás/0000-0001-5198-7210; Szabó, Csaba/0000-0002-1580-6344; Karátson, Dávid/0000-0003-0386-1239} } @{MTMT:33116868, title = {A kitörési központok elhelyezkedésének összefüggése a domborzattal egy miocén ignimbritmezőn}, url = {https://m2.mtmt.hu/api/publication/33116868}, author = {Biró, Tamás and Hencz, Mátyás and Cseri, Zoltán and Telbisz, Tamás Ferenc and Karátson, Dávid}, booktitle = {Calce et malleo – Mésszel és kalapáccsal}, unique-id = {33116868}, year = {2022}, pages = {26}, orcid-numbers = {Biró, Tamás/0000-0001-5198-7210; Hencz, Mátyás/0000-0001-9716-5714; Telbisz, Tamás Ferenc/0000-0003-4471-2889; Karátson, Dávid/0000-0003-0386-1239} } @article{MTMT:32894628, title = {Large-magnitude (VEI ≥ 7) ‘wet’ explosive silicic eruption preserved a Lower Miocene habitat at the Ipolytarnóc Fossil Site, North Hungary}, url = {https://m2.mtmt.hu/api/publication/32894628}, author = {Karátson, Dávid and Biró, Tamás and Portnyagin, M and Kiss, Balázs and Paquette, JL and Cseri, Zoltán and Hencz, Mátyás and Németh, Károly and Lahitte, P and Márton Péterné Szalay, Emőke and Kordos, L and Józsa, Sándor and Hably, L and Müller, S and Szarvas, I}, doi = {10.1038/s41598-022-13586-3}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {12}, unique-id = {32894628}, abstract = {During Earth's history, geosphere-biosphere interactions were often determined by momentary, catastrophic changes such as large explosive volcanic eruptions. The Miocene ignimbrite flare-up in the Pannonian Basin, which is located along a complex convergent plate boundary between Europe and Africa, provides a superb example of this interaction. In North Hungary, the famous Ipolytarnoc Fossil Site, often referred to as "ancient Pompeii", records a snapshot of rich Early Miocene life buried under thick ignimbrite cover. Here, we use a multi-technique approach to constrain the successive phases of a catastrophic silicic eruption (VEI >= 7) dated at 17.2 Ma. An event-scale reconstruction shows that the initial PDC phase was phreatomagmatic, affecting >= 1500 km(2) and causing the destruction of an interfingering terrestrial-intertidal environment at Ipolytarnoc. This was followed by pumice fall, and finally the emplacement of up to 40 m-thick ignimbrite that completely buried the site. However, unlike the seemingly similar AD 79 Vesuvius eruption that buried Pompeii by hot pyroclastic density currents, the presence of fallen but uncharred tree trunks, branches, and intact leaves in the basal pyroclastic deposits at Ipolytarnoc as well as rock paleomagnetic properties indicate a low-temperature pyroclastic event, that superbly preserved the coastal habitat, including unique fossil tracks.}, year = {2022}, eissn = {2045-2322}, orcid-numbers = {Karátson, Dávid/0000-0003-0386-1239; Biró, Tamás/0000-0001-5198-7210; Kiss, Balázs/0000-0003-0040-0656; Hencz, Mátyás/0000-0001-9716-5714; Márton Péterné Szalay, Emőke/0000-0002-2135-8867; Józsa, Sándor/0000-0001-8219-0044} } @CONFERENCE{MTMT:32888412, title = {Preservation of a unique Lower Miocene habitat by a 'wet' mega-eruption: the case of the Ipolytarnóc Fossil Track Site}, url = {https://m2.mtmt.hu/api/publication/32888412}, author = {Karátson, Dávid and Biró, Tamás and Maxim, Portnyagin and Balázs, Kiss and Jean-Louis, Paquette and Cseri, Zoltán and Hencz, Mátyás and Németh, Károly and Pierre, Lahitte and Emő, Márton and László, Kordos and Józsa, Sándor and Lilla, Hably and Samuel, Müller and Imre, Szarvas}, booktitle = {Book of Abstracts (COV11)}, unique-id = {32888412}, year = {2022}, pages = {63-63}, orcid-numbers = {Karátson, Dávid/0000-0003-0386-1239; Biró, Tamás/0000-0001-5198-7210; Hencz, Mátyás/0000-0001-9716-5714; Józsa, Sándor/0000-0001-8219-0044} } @{MTMT:32212805, title = {A KELET-MÁTRAI KÖZÉPSŐ DÁCITTUFA ÚJ VULKA-NOSZTRATIGRÁFIAI EREDMÉNYEI}, url = {https://m2.mtmt.hu/api/publication/32212805}, author = {Cseri, Zoltán and Hencz, Mátyás and Biró, Tamás and Márton Péterné Szalay, Emőke and Lahitte, P and Paquette, JL and Karátson, Dávid}, booktitle = {Átalakulások II.}, unique-id = {32212805}, year = {2021}, pages = {17-17}, orcid-numbers = {Hencz, Mátyás/0000-0001-9716-5714; Biró, Tamás/0000-0001-5198-7210; Márton Péterné Szalay, Emőke/0000-0002-2135-8867; Karátson, Dávid/0000-0003-0386-1239} } @misc{MTMT:32014886, title = {Egy összetett alsó-miocén piroklasztit-sorozat: az "Alsó Tufa" vulkanoszedimentológiai újravizsgálata}, url = {https://m2.mtmt.hu/api/publication/32014886}, author = {Biró, Tamás and Hencz, Mátyás and Karátson, Dávid and Cseri, Zoltán and Jean-Louis, Paquette and Pierre, Lahitte and Prakfalvi, Péter and Hír, János}, unique-id = {32014886}, year = {2021}, orcid-numbers = {Biró, Tamás/0000-0001-5198-7210; Hencz, Mátyás/0000-0001-9716-5714; Karátson, Dávid/0000-0003-0386-1239} }
